+Xiaomi official repair told me that problem is burned charge controller, it’s typical problem for that family, they don’t know which chip to replace and can only replace whole motherboard but it will cost almost same as new laptop.
-Any chance to fix it ?
+Any chance to fix just charge controller ?
Attaching photo of motherboard, could anyone told me where is power controller chip ?
Motherboard rev R10-6050A2789401-MB-A01.
I found only MXIC 25L512e (seems like BIOS) and SIC831 (what is it?) chips on it.
Is needed chip under metalic cover ?
